The union, which was deregistered last Wednesday, was trying frantically to head off labour court action this week, according to Business Report.

CWU, with over 30,000 members, was the largest employee representative grouping under the bargaining council in the information and communications technology sector.

The publication reported that CWU's troubles began in November when the department accused it of contravening sections 98, 99 and 100 of the Labour Relations Act by failing to provide financial statements since 2006.

It had also reportedly ceased to function in terms of its constitution.

Attorney for CWU, Thando Faku said the union planned to take legal steps.

"It's true. I'm trying to arrange for a date now."

Gallant Roberts, CWU's general secretary, reportedly said the trade union was baffled and amazed as the department had failed to explain the reasons for the deregistration.

"We are likely to be appearing on this matter on an urgent basis. We are likely to be submitting documents tomorrow."

According to Business Report the department said it would continue with its process.

Spokesman Page Boikanyo said the union repeatedly failed to provide audited statements as required by law.

"They have a right to challenge it in court or have their statements audited. After that process they may reapply."
